Answer Happy

When Rob became interested in electricity, his clear-headed father considered the boyג€™s fancy to be instructive as well as amusing; so he heartily encouraged his son, and Rob never lacked batteries, motors, or supplies of any sort that his experiments might require.He fitted up the little back room in the attic as his workshop, and from thence, a network of wires soon ran throughout the house. Not only had every outside door its electric bell, but every window was fitted with a burglar alarm; moreover, no one could cross the threshold of any interior room without registering the fact inRobג€™s workshop. The gas was lighted by an electric fob; a chime, connected with an erratic clock in the boyג€™s room, woke the servants at all hours of the night and caused the cook to give warning; a bell rang whenever the postman dropped a letter into the box; there were bells, bells, bells everywhere, ringing at the right time, the wrong time and all the time. And there were telephones in the different rooms, too, through which Rob could call up the different members of the family just when they did not wish to be disturbed.His mother and sisters soon came to vote the boyג€™s scientific craze a nuisance; but his father was delighted with these evidences of Robג€™s skill as an electrician and insisted that he be allowed perfect freedom in carrying out his ideas.The authorג€™s purpose for the second paragraph is:

A. to show how ingenious Rob was
